Oracle 12c database NOLOGGING

Question

Our database is Oracle 12c and we have some temporary tables created with NOLOGGING option.

My concern is in case of database recovery can we recover those tables(i'm interested only for the DDL structure of course, no data)?

Thank you.

Answer 1

When you create a table or index as NOLOGGING , the database does not generate redo log records for the operation. Thus, you cannot recover objects created with NOLOGGING , even if you are running in ARCHIVELOG mode, only a small set of metadata is written to the redo logs.

Please check this where it gives the process on how to retrieve the data when nologging mode is set to on.
